DOVER, Del.—NASCAR, which has banned teams from testing cars at tracks that play host to NASCAR's three national series since 2009, will allow each organization four tests in 2013.

The number of cars the teams can bring to the test — on a day of the organization's choosing — remains to be determined, NASCAR vice president of competition Robin Pemberton said Saturday at Dover International Speedway.

"We feel it's time to open that up and allow the teams to manage their testing and get back on facilities that host our events," Pemberton said. "Four felt like a reasonable number."

Daytona test tentatively scheduled for Jan. 10-12 won't count against the four tests.

The testing ban was instituted in 2009 to save teams money. But teams have often gone to non-NASCAR national series tracks to go test their vehicles.

Testing will take on additional importance in 2013 as teams begin working with the second generation of the car introduced in 2007. New car bodies have more distinct manufacturer identifiable characteristics.

NASCAR will conduct a test of the 2013 car Wednesday at Talladega with eight cars expected. NASCAR and Goodyear will conduct tire tests of the 2013 car Oct. 9-10 at Texas. Then teams can bring a 2013 car for the Oct. 17-18 open Cup test at Kansas that proceeds the race weekend on the track's new pavement.

There will be another Goodyear test Oct. 23-24 at Phoenix. Teams also will test Nov. 6-7 at Charlotte.

Pemberton said he expects seven or eight organizations to come to the tests at Talladega and Charlotte. Four teams typically conduct the tire tests.
